Projects come up with many difficulties simply because the creators lack clearly defined and documented requirements. Because of that having a good Requirement Management system is very important. Requirements management is a systematic method for finding, documenting, organizing and tracking requirements along with the changes that may occur. Requirement management helps to make sure that the client gets exactly what he needs and meets all the requirements he needs.

A vital step in requirement management is always to determine and agree upon unique requirements gathering processes, documentation regarding requirements, tractability and testing anticipation. Requirements are defined during the planning phase and they are managed throughout the entire process from high level requirements, through detailed requirements, layout, build and test. In this requirement management strategy there are many steps that needs to follow when it comes to requirement management.  It’s very important to follow them in order to prevent unnecessary problems.


Requirement management process is common to all organizations. Because of that, the objective of this document would be to provide assistance with all the needs in requirement management and it will describe the practice review, requirements, best practices, activities and key terms related in order to these needs. Requirement management is a key to a successful path so it is very important to have a good knowledge regarding this.

Requirement Management Strategy

Requirement Investigation

As the first step of Requirement management, Requirement Investigation is very important. In this stage there are three classes of requirements which are gathered from the user, the business and the development team. Asking questions such as,

  • Problem we are trying to solve?
  • Requirement to solve this problem?
  • How the problem can be solved?

By asking these kinds of questions you can identify the goals, needs and purposes of the product. After understanding these requirements functional requirements can be developed.

Functional requirement

A function is referred to as some inputs, the actual behavior and outputs. It may be calculations, technical facts, data manipulation and processing along with other specific functionality. A standard functional necessity will include a unique name and amount, a simple summary, plus a rationale. These details are helpful to guiding the reader to realize why the requirement should be used, and to be able to track the requirement through the development of the system.

In order to identify the goals of the program or product, we need to gather information regarding requirements and find out the problem which has to be solved. Methods to gather information can vary in order to achieve this. Some of the methods will be only appropriate for some circumstances. Some of the methods that you can use are:

  • Interviews
  • Prototyping
  • Surveys
  • Focus group
  • Workshops
  • User stories
  • Use case analysis


Interviews could be a very useful feedback instrument, but it can even be very time-intensive because they require one-on-one discussion. Interviews may be open-ended, which may make the information they obtain harder collect and to analyze. More organized interviews will help to make data gathered much easier & to get better information to fit in to your analysis.


Especially in software engineering, prototyping is a technique for creating a quick and rough version of a desired program or aspects of that program. It serves as a communication mechanism, allowing reviewers to understand and interact with the system.


Surveys and questionnaires can allow you to reach a large audience. Moreover, by using specific questions, you can get a clear data set. Unfortunately, surveys tend to have an incredibly low response rate. In surveys, if you can ensure that survey questions are on issues of interest & let participants know how the survey will benefit these individuals, then using surveys you can gain a big audience.

Focus group

A focus group can be viewed as a group interview. It generally involves six to twelve persons inside a facilitated discussion on a clearly defined topic. Focus groups are useful especially in order to create a dialogue on your program. Respondents can interact not just through an interviewer but also jointly. Since other people’s opinion can be taken into consideration, focus groups can be rally effective.


Requirement gathering workshops offer an opportunity for individual perspectives to become shared, refined and combined in manners which will benefit and develop their business requirements. People can justify their views in front of a large crowd and in this way large amount of information can be gathered since there are lots of people involving.


After finishing gathering information we will know the problem that we need to solve. Then we can go to the next question what are the requirements to solve the question? One of the thing you need as a requirement is the money or in other words, knowing the cost of the product/process.

Within this stage, prices are determined. With regard to individual requirements, the current price tag of work is compared to the future projected costs if the revolutionary system was in place. Technical costs are linked to software development prices and electronics prices. The team ought to look into newest automated tools and sufficient processing power to shift some of the burden from an individual to the system just to save people time.

The question also highlights a fundamental point about demands management. A human and a tool form a system and this realization is especially important if the tool is often a computer or a new application which is in a computer. The human mind performs exceptionally well in parallel processing and meaning of trends with insufficient facts. The CPU excels in serial running and accurate mathematical computation. The overarching goal of the prerequisites management effort for a software program project would thus be to ensure the work being automated gets assigned to the proper processor. The deliverable from the Feasibility stage could be the budget and schedule for the particular project.

If the project is over budgeted, the designers or the owners can think of ways to reduce it and make the budget affordable. Also, there are many advantages of calculating the cost and this will keep you away from many problems. In requirement management this is one of the most important step that you need to keep an eye on.

Analyzing & Designing

Analyzing and designing is also an important part in requirement management. The aim of the investigating activity would be to transform technical requirements into informal requirements by making sure they reflect the product quality attributes & it express the requirements of the client. Nearly all requirements analysts find augmenting textual demands with modeling valuable, whether what this means is drawing pictures over a whiteboard, utilizing display tools for instance presentation or just creating a mental model. These representations ought to be managed along with the requirements to help ensure consistency, trace-ability and also change control. Visual demands modeling gives a simple and also powerful solution to communicate. It also helps to clarify demands and develop a common realizing between all development associates and stakeholders.

In order to design analyzing can be done by following below steps.

  • Input – To analyze, first you need to gather all the information you got from the client. We can call that as Input.
  • Categorize – Requirements tend to be decomposed directly into basic types and cohesive items. These can be along functional liner or it can be along performance line.
  • Decide Quality Attributes – Each and every requirement can be reviewed against a collection of project-defined capabilities. Requirements that do not reflect the required attributes involve further refinement.
  • Tracing Requirements – Tracing requirements can be considered as following & describing the project’s life cycle. Requirements tracings will captures all levels of requirements as well as it will help to ensure that the project meets buyer expectations. These requirements will change to project to project so you have to understand the requirements exactly. There are types of requirements such as,
    • Functionality
    • Dependability
    • Usability
    • Supportability
    • Performance
  • Reconciling Requirements – This step is to ensure that in the requirement management process, customers’ needs are correct and complete. By getting more information from the Requirement Investigation step, reconciling requirements can be successfully achieved.
  • Decision – Record any decision rationally and it will be easy to get information in the future if needed. Trade studies could be performed to help record the rationale
  • Output – Using many steps or all the steps and combining them will give a good analysis of the product.

After finishing analyzing it is easy to do the designing part. Since you have all the information you need, and you have analyzed them very well, there is a lesser chance that you will get something wrong.

Construction and Testing

In the construction and testing stage, as for the requirement management, it is important to make sure that the cost stays within schedule & budget. When building a software application, the interface can be created on a paper and tested using potential users while framework of the software program is still being built. Results of these kinds of tests are recorded in a user interface layout guide and handed off towards the design team and then they will develop the user interface. This saves their time which enable it to make their jobs much easier.

As much as construction is important testing is important too. When testing the product/software, the creator of the software or particular product can find out if there’s anything wrong with their product or not. An excellent way to manage requirements is to ensure they are clearly mapped to test cases. Making sure each need is clearly verifiable instantly, not only helps to prepare later phases through the project, but it also puts your writer to the correct mind-set. Requirements and their associated tests might also want to indicate what the system should never do and what happens while using the limits. Organizations that make sure that their requirements are testable can improve the project success and gain more quality to the project.

Requirements change management

Change of requirements can happen especially in software development. Even after the project is completed, clients may have some different opinions that the developer may have to execute. Activities of requirements change management contains getting change requests from the stakeholders, recording the received transform requests, analyzing and deciding the desirability and technique of implementation, implementation with the transform request, quality assurance for your particular implementation and closing the change request. Then the results associated with change requests will be created, analyzed and correct metrics are derived and dovetailed towards the organizational knowledge library.


Even after you deliver your product, requirement management won’t stop. Whenever a good requirement is written in a previous project rather than writing again, the previous one will be reused. Generally, this occurs by copying and pasting them. By reusing, we can save time. In addition, since you have gained previous experience, you can present more suitable and effective requirements.

As in the above content of the article it is clear that requirement management is very important. Requirements definition and administration are usually extremely important routines in any task and attempting on this route could strengthen and accelerate Returns on investments. Even though you work hard, if the requirements are not clear, you will get a wrong product and you will fail your business.
